    • A clutch or brake assembly is disclosed for controlling the relative rotation between two rotary members. Wedge means are carried between a pair of facing cam plate surfaces by an axial core member. The wedge means are axially movable with respect to the core member but prevented from rotating about the core member. The wedge means extend beyond the ends of the core member but, when the cam surfaces are aligned, are spaced therefrom to permit relative rotation between cam surfaces and the core member. When the cam plates are moved out of alignment, the distance between them is less than the axial length of the wedge means, causing the wedge means to wedge tightly between the cam plates. Because the wedge means is prevented from rotating relative to the core member, when it is wedged or locked between the cam plates they are also prevented from rotating relative to the core member.
    • 公开了用于控制两个旋转构件之间的相对旋转的离合器或制动器组件。 楔形装置通过轴向芯部件承载在一对相对的凸轮板表面之间。 楔形装置相对于芯构件可轴向移动,但是防止围绕芯构件旋转。 楔形装置延伸超过芯构件的端部,但是当凸轮表面对准时,与楔形构件的间隔开,以允许凸轮表面和芯构件之间的相对旋转。 当凸轮板移出对准位置时,它们之间的距离小于楔形装置的轴向长度,导致楔形装置楔紧在凸轮板之间。 由于防止楔形装置相对于芯构件旋转,所以当它们楔入或锁定在凸轮板之间时,它们也被阻止相对于芯构件旋转。
